I have no Galaxy S Epic to test with, and I essentially use something like if (camera.getParameters().getFlashMode(camera.getParameters()) != null) parameters.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH)
to turn on the torch, so from your description I gather that this ought to work also on the Galaxy. However, I used FLASH_MODE_OFF to turn the torch LED off, which works fine on the HTC Desire with Android 2.2, but according to your description this would fail with the Galaxy. You can try my app "The vOICe for Android" (search Market for "seeingwithsound", and toggle the color identification on/off via the Menu key (second entry) to see if indeed it fails to turn off the torch when done with the color identification feature. You could use this to validate your analysis of the Galaxy S Epic.
